Why is the temperature difference between mountains so big?

This is caused by the alpine climate. The climate on the mountain is extremely unstable and changes quickly when it is flat. This is because of the air in the mountains.

The temperature changes rapidly and the temperature difference (temperature difference) is relatively large. About 15-20 degrees. flat

The temperature difference is less than 10 degree.

Low temperature, low air pressure. Since the sea level, the temperature has dropped by about 6 degrees for every rise of 1000 meters. Therefore,

Even if the temperature at the foot of the mountain is as high as 30 degrees Celsius, the temperature of Yushan Mountain, which is 4000 meters above sea level, is only about 10 degrees Celsius.

As for air pressure, it is inversely proportional. The higher the altitude, the lower the air pressure. Under standard conditions, every 100 meters, gas

Pressure drop 10 mbar. At 750 mbar, the peak height of 4000 meters is about 460 mbar. The phenomenon of low pressure is very important.

The effects on the human body are shortness of breath, loss of appetite and other symptoms, which is a sign of mountain sickness.

There is much dew and strong wind. Because the climate on the mountain is changeable in a day, whether it is summer or winter,

Often the fog comes and the whole mountain falls into a white world. Will suddenly reduce the visibility around,

It is easy for people to encounter fog in the lost season. The low temperature and the humid air brought by fog have created this storm.

Exposing the epidermis is easy. Why is there wind on the mountain? That's because the terrain on the mountain is very different.

The ground receives solar radiation heat, and due to uneven heat distribution, air flow often occurs.

And because the resistance of airflow on high mountains is much greater than that of wind.

There is frost and snowfall in winter, and there are many hot thunderstorms in summer. There is a lot of hail when it rains. Hot thunderstorms in the mountains in summer are mostly in the afternoon.

3-6 o'clock, the phenomenon is moderate, with showers.
